WHEEL CLAMP OR ANCHOR.

Specification of Letters Patent.

' Patented Oct. 8, 1907.

Application filed Jnne 18, 1907- Serial No. 379,562.

Toall 'whom it may concern:

Be it known that MARTIN PAUrlsoN, a citizen ofthe United States,residing at Omaha, in the county of Douglas `and State of Nebraska, hasinvented certain new and useful lmprovernentsin Wheel Clamps or Anchors,of which the following is a specification.

This invention relates to an improved wheel clamp or anchor for useparticularly upon wheels oi railway cars, and has reference to theconstruction of an angularly formed metal plate which, in connectionwith a liiting jack and a horizontally-disposed sustaining bar, may beused for the purpose of anchoring a wheel to a railwaytrack when raisingthe bearings of a car from the journal. The device is used for thispurpose. when, for any reason, the journal becomes overheated fromfriction, o r when, according tol railway terms, the journal box becomesa hot box.

The invention has for its object the presentation of a bar having a flatbody provided with upwardly-extending arms with holding-heads formed attheir ends, one of the arms being of a length so that its holding-headwill engage the annular rim adjacent the tread of the wheel when thebody of the bar rests upon a railway tie, the shorter arm being for usein connection with a sustaining-plate when the wheel is not directlyabove the tiel The invention also includes the form,oi an anchor foundto be highly efficient for the purposes de-- signed, and which conducesto economy in use of material. `With these and other objects in view theinvenl tion presents a new construction and arrangement of parts fullydescribed herein, pointed out by and illustrated in the drawings',wherein,-

Figure 1 is a plan view of a wheel clamp or anchor em- Fbodying myinvention. Fig. 2 is a vertical, side view of the invention. Fig. 3 is aplan view, somewhat reduced, showing the form oa bar before being bentto form the wheel anchor. Fig.` itis a vertical side view of theinvention, 'showing the short armin engagement with the annularrim'adjacent the tread of a car wheel,

the journal box, sustaining-plate and a part of the wheel and bearingsbeing in section. Fig. 5 is an end view of the wheel anchor, the shortarm vbeing presented at the iront. Figf is a view somewhat similar tothat of Fig. 4, showing, however, theuse of the long arm of the anchor,and showinglthe journal box and bearings thereon raised above thejournal, so thatthe saddle and brass plate may be removed. Fig. 7 is aside view oi a fragment oi railway track,` a car wheel thereon whosecenter is disposed vertically between the railway ties, and showing theuse of niy invention in connection with a sustaining plate, the long armof the anchor being removed to obtain a view of other parts.

lteierring now to the'drawings for a more particular the claimsdescription, numeral 1 indicates a wheel anchor, being a lat metal barhaving a rectangular lbase 2. vits ends Iformedoutwardly convergent andbent upwardly and inclined outwardly from base 2te forma long arm 3 anda short arm 4, said arms near their terminals being extended outwardlyfrom and substantially parallel with the base to form holding-heads 5,these heads being downwardly and transversely convergent at theirextremities to fornrcontact-blades 6. Base 2 upon its lower surface isprovided with holding-lugs 7, and upon its upper surface adjacent arms3.and 4 are formed rugose areas 8. v

By referring to Fig. 3 it will be seen that the edges of 4 theend-portions of plate or-bar2 are tapered from points a a and b b to therespective ends c and d oi the plate, and the tapered part e used forthe long arm 3 is longer than the tapered part f used in forming theshort arm, and this is'the preferred construction, as in manufacturingthe device it effects a large saving' inv the cost and weight ofmaterial; arm 3 as well as arm 4 is regularly divergent from the base tothe terminals c and d, respectively;`the tapered parts e and f arepreferably formed with facets g and h, which incline inwardly from theirouter surface, this being an, advantage to decrease weight and cost ofmaterial. In operation, when the car wheel 9 having a ,hot box has itsvertical center above a railway tie, the long arm 3 ofthe anchor may beused, as shown in Fig. 6, the length of said arm being sufficient topermit its the tread of..wheel 11 at a .time when base 2 is resting upontie -12; a lifting .jack 13 is then placed between4 base 2 and strap 14upon which the joui'nal box 15 rests, and by means of lever 16 upon thejack, the journal box may be raised.

The functions performed by the device will be readily appreciated bythose conversant with railroad work, for when a hot box is discovered,as frequently happens, the train must be brought to a stand-still andbrass plate 17 removed; The weight of the car is sustained by straps 18which rest upon axle-guard 19; the weigl1t by this contact istransferred to the slide or saddle 20; saddle 20 rests upon brass plate17. The journal 21 has a terminal flange 22 which prevents endwisemovement raised upward while the wheel is detained or anchored tothetrack, and this is accomplished in the manner already described, so thatsaddle 2O and brass plate 17` may be removed.

above a railway tie the short arm 4 of the wheel anchor -is then used,as shown 'in Figs. 4 and 7, at which time contact-blade to engage theannular rim 10 adjacent y of brass plate 17, and there/fore, to removeplate v17 the weight of the car must be overcome and these parts If thevertical center of the wheel is not disposedy sustaining-plate 2'3 isemployed. Arm 4 has a` length when base 2' is seated upon thesustaining-plate, to cause its rcontact-blade to engage rim 100i thewheel, and the operation thereafter is the same as heretofore described.

The operation is more satisfactory in many respects when the Wheel andjournal box are directly above a railway tie so that the anchor may restupon the tie, but by use of the short arm, in connection withplate 23,the operation is certain regardless of the position of the journal box;and the employment of the device, in connection with the partsdescribed, furnish a means or removing brass plate 17 with a greatsaving of time.

'The `considerable weight of the car causes lugs 7 to engage the tie orsupport upon which the anchor rests, and this feature is importantsincethe tie is often covered With ice or accumulated soil.

It will be understood that rim l() is found upon the outer surface ofall car Wheels,`this rino being adjacent the tread of the wheel; andcontact-blade 6 in connection With the use of lugs 7 furnish a reliablelmeans for detaining the wheel when raising the journal box. The rugosesurfaces 8 furnish aA reliable seating for the basati the lifting jack.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

1. A Wheel clamp having a rectangular base with endportions extending`outwardly and above the plane of said A base to form divergent arms,said divergent arms having end-portions bent to extend outwardly andsubstantially parallel with said rectangular hase to form holding-heads.

2. t wheel clamp or anchor having a rectangularl base with end-portionsextending outwardly and above the plane of Said hase to form divergentarms, said divergent arms having end-portions bent to extend outwardlyand substan tially parallel with said rectangular base to formholdingheads; one of said divergent arms having a length less than theother of said divergent arms.

3. A wheel clamp or anchor having a reetangularly formed base withend-portions extending above the plane of'the base and outwardlytherefrom to form divergent arms, said divergent arms havingend-portions bent to extend outwardly and substantially parallelwitlrsaid rectangular base to form holding-heads; said'holding'headsprovided with downwalilly-extending terminals to form contact-bladestransversely with reference' to said rectan- ,aularly formed base.

4. A wheel clamp or anchor having: a rectangular hase with end-portionsextendingY outwardly and above the plane of the hase to form divergentarms. said diveinent arms having' end-portions bent to extend outwardlyand substantially parallel with said rectangular base to formholding-heads. one of said divergent arms haviuj.: a length less thanthe other of said divergent arms; said holding;-

4heads provided with downwaidly-extending terminals tu formcontact-blades transversely with reference tu saidrcctane'ularly-t'ormed base.

In testimony whereof he has atlxed his signature lu presence of twowitnesses.
